摘要

我们展示了当用体积平均压实函数表示时，为什么原始黑洞形成的阈值是普遍的（与扰动的形状无关）。这个证明是基于临界引力坍缩现象的自相似性。

Why the universal threshold for primordial black hole formation is universal

We show why the threshold for primordial black hole formation is universal (independent from the shape of the perturbation) when expressed in terms of the volume averaged compaction function. The proof is rooted in the self-similarity of the gravitational collapse phenomenon at criticality.
